..Cross-twin cross-trait correlations suggested small shared genetic effects between RRBIs and other symptoms. These findings from a clinical sample of twins indicate a fractionation of social/communicative and RRBI symptoms in ASD...

..Social and communication ability was significantly associated with prospective remembering in an everyday memory context but not with the CAVLT-2. The complex nature of everyday memory and its relevance to ASD is discussed...

..Though IT was not significantly faster in the ASD group than in the matched control group, the relationship between IT and IQ was uniquely discrepant for the ASD group, partially corroborating and extending previous findings...

A prospective longitudinal study of children's theory of mind and adolescent involvement in bullying

..It is important for healthy social relationships and thus may contribute towards children's involvement in bullying. The present study investigated whether children involved in bullying during early adolescence had poor ToM in childhood...

Connectivity and the corpus callosum in autism spectrum conditions: insights from comparison of autism and callosal agenesis

..Last, study of AgCC shows that it is possible, in some cases, to develop good social cognitive skills in the absence of the corpus callosum, presenting a challenge to future connectivity models of autism...

Salient social cues are prioritized in autism spectrum disorders despite overall decrease in social attention

..g. calendars, art, music) that capitalize upon strengths often associated with ASD, such as detail-focused processing, are probably further enhanced through over-learning and massive exposure, and reflected in atypical brain structure...

The 'fractionable autism triad': a review of evidence from behavioural, genetic, cognitive and neural research

..Extant studies of memory shed limited light on this issue as they involved either laboratory-based tasks or protocols that varied between participants...

Autism and pitch processing splinter skills: a group and subgroup analysis

Pamela HeatonGoldsmiths College, London, UKAutism 12:203-19. 2008

..The findings were interpreted within the context of neuroconstructivist models of typical development and delayed language acquisition characteristic of autism and other neurodevelopmental disorders...

A training study of theory of mind and executive function in children with autistic spectrum disorders

..No improvement on the executive function tasks was seen in any of the groups. The implications of these findings are discussed...

Time to give up on a single explanation for autism

Francesca HappeFrancesca Happé, Angelica Ronald and Robert Plomin are at the Institute of Psychiatry, Kings College London, De Crispigny Park, London SE5 8AF, UKNat Neurosci 9:1218-20. 2006

..Twin data suggest largely nonoverlapping genes acting on each of these traits. At the cognitive level, too, attempts at a single explanation for the symptoms of autism have failed. Implications for research and treatment are discussed...

..Additionally, these findings lend support to forthcoming DSM-5 changes to ASC diagnostic criteria that will see language difficulties separated from the core ASC communication symptoms, and instead listed as a clinical specifier...
